CT scan can be done in order to define the relationship of desmoid tumor to adjacent structures, assess resectibility and find out the need for treatment. On CT scan, desmoid tumor is characterized by a homogeneously or focally hyperattenuating well circumscribed mass which may demonstrate enhancement following administration of intravenous contrast.
Abdominal computed tomography (CT) and positron emission tomography (PET) of the desmoid tumor. (a) CT shows a solitary and localized tumor in the mesentery of the transverse colon 27 months after gastrectomy (arrow). (b) PET shows radiotracer fluorodeoxyglucose uptake of the tumor (arrow). (c) CT and (d) PET of the tumor after five courses of chemotherapy, showing that no significant clinical response was seen (arrow).Source: Okamura A. et al, Department of Surgery, School of Medicine, Keio University, 35 Shinanomachi, Shinjuku-ku, Tokyo 160-8582, Japan
